Mitella

Mitella is a genus of flowering plants known as miterworts or bishop's caps. Mitella species are native to temperate and arctic North America and Asia.

Description
Mitella includes perennials growing from a scaly rhizome, bearing wide heart- or spade-shaped leaves near their bases and flowers with five petals in a long raceme or spike.

Etymology
The genus name means "little mitre", from Latin mitra with the diminutive suffix -ella, since the flowers are said to resemble bishop's headdresses. In Classical Latin use, however, mitella means "female headdress" or "sling". Latin mitra comes from Greek mítrā "girdle", "headband", or "turban".

Species
Four species and natural hybrids are accepted.
 * Mitella diphylla L. - twoleaf miterwort
 * Mitella × inamii Ohwi & Okuyama
 * Mitella × intermedia Bruhin (M. diphylla × M. nuda)
 * Mitella nuda L. - naked miterwort (syn. Mitella prostrata - creeping bishop's cap)
